Have some GeoNews that doesn't fit in another category? Here's the place. Try to keep it at least somewhat on topic.
Dr. Peter Rankilor, a pioneer in the geosynthetic, geotextile and geomembrane industry was recently sentenced to 10 years in prison as a result of his January conviction on “indecent assault and incest” charges stemming from […]
[Editor] Last week was the International Foundation Congress and Equipment Exposition in Orlando, Florida. The event was co-sponsored by the Geo-Institute, ADSC and PDCA. Perhaps at the next event I’ll be able to attend and provide some comprehesive coverage via GeoPrac. In the meantime, I am very appreciative of Robert Thompson of Dan Brown and Associates, PLLC. who was among the attendees (and a presenter?). He was kind enough to provide GeoPrac readers a summary of the event. Click through for more on this tremendous conference. (Photo by Robert Thompson, Dan Brown and Associates, Inc. ) [/Editor]
The International Foundation Congress and Equipment Expo is underway in Orlando, FL. This is one of the biggest geo-conferences out there and is sponsored by ADSC, The Geo-Institute and PDCA with the cooperation of 15 […]
A recent Reuters article described how Liquefied Natural Gas or LNG projects are weathering the global recession better than other industries. It states that one reason is the continuing global demand for natural gas and […]
Details are starting to solidify related to the construction-related spending in the Economic Stimulus Package. According to ENR.com, the total estimated construction-related spending is around $131 billion. They have a very nice breakdown of the spending, sector by sector (updated 2/13). Read on for the highlights. (Photo by SP8254)
That’s the title of a blog post by Loren Faulkner of California Builder and Engineer, an Associated Construction Publication. He cites a recent survey by the American Society for Quality (ASQ). ASQ/Harris conducted its survey […]
The good folks at Geology.com have pointed out a very interesting and alarming article on hazardous chemicals that may be used in the Hydrofrac process of natural gas extraction and their impact on groundwater. The […]
Most carbon sequestration approaches focus on injecting CO2 underground for storage in porous aquifers and hoping the gas doesn’t escape. There are other problems with this approach as well, including chemical reactions that create Carbonic […]
The Arizona Research Institute for Solar Energy (AzRISE) and the Laboratory for Advanced Subsurface Imaging (LASI) at the University of Arizona, together with Southwest Solar Technologies, Inc., are investigating the use of excavated cavities for […]
The Progressive Engineer website has an interesting article profiling Colwyn Sayers, a geotechnical engineer with the Lexington, Kentucky office of Stantec. His specialty is inspecting underwater bridge foundations which requires either wetsuit or drysuit diving using topside air sources. Occasionally a hyperbaric chamber is required as well.

On a typical dive, Sayers looks for signs of deterioration that may cause instability or even collapse of the bridge. This includes scour, undermining from flowing water that erodes the streambed, deterioration, cracks, section loss, and impact and abrasion damage from trees. Tree debris caught in the bridge leads to scour and erosion. “It depends on the construction type as well as the materials on the bridge,” he states.
